Specification of Letters Patent.

Application filed April 15, 1911.

Patented Sept. 19, 1911.

Serial No. 621,221.

To all whom it may concern:

Be it known that I, VVALTER E. BROWN, a citizen of the United States,and a resident of Herrick, in the county of Grregory and State of SouthDakota, have invented certain new and useful Improvements inCultivators, of which the following is a specification.

My invention is an improvement in cultivators, and consists in certainnovel constructions and combinations of parts hereinafter described andclaimed.

Referring to the drawings forming apart hereof, Figure 1 is aperspective view of the improvement from the rear, Fig. 2 is a planview, and Fig. 3 is a vertical longitudinal section.

The present embodiment of the invention comprises an axle 1, havinglaterally offset alined spindles 2, on each of which is journaled awheel 3, and the spindles are connected to the body of the axle byangular portions 4. The axle is thus substantially U-shaped.

A tongue 5 is provided, and an arch is arranged in front of the axle.The body 6 of the arm 12 is substantially parallel with I the body ofthe axle, and the arm 7 extends downwardly, and each arm is connected tothe adjacent portion 4 of the axle by a link 8.

Each link 8 is pivoted to the arm 7 at one end as shown at 9, and at theother, is connected to a hanger 10 encircling the arm 4. Plates 11 areprovided at one end with openings for receiving the body of the axle,and at the front end each of the said plates is bent inwardly at anangle, as shown at 12,

and is connected to the tongues, one on each side thereof.

The rear end of the tongue is provided with a plate 13, having at itscenter a hub or bearing 14. The rear end of the plate extends above thebody 6 of the arch, and a crank arm comprising two laterally offsetconnected journal pins 15 and 16 is connected with the plate.

The journal pin 15 is journaled in the bearing. 14, and in an opening ina plate 17 on the lower face of the tongue. A lever 18 is journaled witha bearing 19 at its front end journaled on the journal pin 15. A washer2O encircles the pin above the arm, and a cotter pin 21 is passedthrough the pin above the washer. The rear end of the lever extendsbehind the axle, and a seat 22 is secured on the said end.

A hanger 23 is pivoted to the arm directly above the axle, and a pulleyor grooved wheel 24 is ournaled in the hanger. The wheel 24 is on asleeve 25 which encircles the axle body, between the portions 7 4. Thearm is also provided with a bearing 26 near its forward end.

A link 27 is provided at each end with 5 angular portions, one of whichis engaged with the bearing 26, and the other with a perforated lug 28on the adjacent plate 11. The forward ends of the portions 12 of theplates 11 are connected with a box or sleeve 29 on the tongue, and ajournal pin 30 is passed through the sleeve and is engaged by a nut 31to hold the sleeve in place.

The sleeve is of greater size than the tongue, so that the tongue isfree to rock laterally, as indicated in dotted lines in Fig. 2. When thefront end of the tongue swings toeither side, the seat is swung in thesame direction, the lever 18 swinging in the link 27 as a fulcrum.

The journal pin 16 of the crank arm is journaled in a bearing 32 on thebody 33 of a yoke, whose arms 34 are connected by a bar 35, having atits center an upwardly offset part 36. A foot rest or step 37 isattached to each arm 34 at its junction with the bar 35.

The cutting disks 38 are supported from the bar 35, one set on each sideof the portion 36, and the rear end of the frame, formed by the yoke andthe bar, is supported by springs 39, which encircle rods 40, connectedat one end with the ends of the bar, and passing at the other throughbearings 41 on the sleeve 25.

This cultivator and adjusting mechanism form no part of the invention,however, the invention consisting in the connection be tween the seatand the tongue. The operator when seated in the seat 22, with his feeton the rests 37, may swing the frame 33, 34, 36 in either direction.When the seat is moved to one side, the lever 18 is swung laterally.

In operation when the operator is seated, and the machine is movingforward, and it is desired to shift the pull on the disks or shovels toone side or the other. the operator pushes with the right or the leftfoot on the rest 37, swinging the seat in the opposite direction. Theportion 16 of the crank arm is swung laterally in the opposite directionto the seat, and the disks or shovels tend to move in the samedirection. It will be evident that but slight strength is necessary forthis movement, so that the operator has complete and easy control overthe machine, permitting him to follow the row closely without coveringor plowing up plants that may be at one side of the row. The disks orshovels may be thus guided to follow the row, regardless to a certainextent of the position of the supporting frame. Since this movement isbrought about by the operator and his feet, both hands are left free foroperating the other parts of the machine. It will be evident that agreat saving of time is thus effected, as well as a saving of strengthon the part of the operator. For road travel the lever 18 is locked atthe center of the machine by means of the hook 18, which is engaged withthe eye 15 on the lever.

I claim 1. In a cultivator, the combination with the frame and wheelsfor supporting the frame, of a tongue, a pivotal connection between thetongue and the frame near the rear end of the said tongue, a. crankhaving one arm journaled in the tongue, a lever pivoted at one end tothe said crank arm, a seat connected with the other end of the lever,said lever extending behind the frame,

a foot rest on the frame near each side thereof, a bar supported by theframe above the same, a stirrup hanger pivoted to the lever, a groovedroller journaled in the hanger and engaging the bar, a rigid linkpivoted at one end to the frame and at the other to the lever near thecrank, an auxiliary frame having a bearing at its front end forreceiving the other arm of the crank, a swinging connection betweenthe-rear end of the auxiliary frame and the main frame, cultivatingmeans supported by the auxiliary frame, and means for locking the leverfrom swinging movement.

2. In a cultivator, the combination with the wheel supported frame, of atongue to the lever intermediate the seat and the crank arm, anauxiliary frame having a bearing at its front end for receiving theother arm of the crank, a swinging connection between the rear end ofthe auxiliary frame and the main frame, a bar supported by the framenear the front thereof, a pulley journaled on the lever and running onthe bar, means for locking the said lever from movement, and cultivatingmeans supported by the auxiliary frame.

3. In a cultivator, the combination with the wheel supported main frame,of an auxiliary frame supported below the main frame, a connectionbet-ween the rear ends of the said frames, a tongue pivoted to thefrontend of the main frame, a crank having one arm journaled in thetongue behind the said pivotal connection and having another armjournaled on the front of the auxiliary frame, a lever pivoted at oneend on the said first-named arm of the crank, a seat on the other end ofthe said lever, a track supported transversely of the main frame, aroller on the lever running on the track, cultivating means supported bythe auxiliary frame, and a pivotal connection between the frame and thelever intermediate its ends.

4. In a cultivator, the combination with the wheel supported main frame,of an auxiliary frame supported below the main frame, a connectionbetween the rear ends of the said frames, a tongue pivoted to the frontend of the main frame, a crank having one arm journaled in the tonguebehind the said pivotal connection and having another arm journaled onthe front of the auxiliary frame, a lever pivoted intermediate its endsto the main frame and pivoted at its front end to the auxiliary frame, aseat on the other end of the lever, and detachable means for preventingswinging of the lever.

5. In a cultivator, the combination with the wheel supported main frame,of an auxiliary frame supported below the main frame, a connectionbetween the rear ends of the said frames, a tongue pivoted to the frontend of the main frame, a crank having one arm ournaled in the tonguebehind the said pivotal connection and having another arm journaled onthe front of the auxiliary frame, and a lever pivoted intermediate itsends to the main frame and pivoted at its front end to the auxiliaryframe.
